How to Install the Sequestr External Disconnect Enclosure

This guide provides step-by-step instructions for installing the Sequestr external disconnect enclosure to a control enclosure, ensuring proper mounting, wiring, and initial setup.

Estimated time: 1h

Tools needed:

Screwdriver, Wire strippers, Multimeter, Drill

Supplies needed:

Mounting screws, Terminal connectors, Hoffman hole seal, Hoffman blank adapter plate

  1. Power Down the System

    Turn off the local disconnect in the control enclosure and the feeder disconnect. Wear appropriate Personal Protective Equipment (PPE) and open the control enclosure. Use a voltmeter to test for power on the incoming side of the disconnect.

  2. Mount the Sequestr Enclosure

    Remove the subpanel from the Sequestr enclosure. Drill and deburr a hole for the power line entrance. Hang the Sequestr enclosure on the control enclosure using M6x16mm bolts and secure it with washer head cap screws from inside the control enclosure.

  3. Install the Circuit Breaker

    Drill mounting holes in the panel for the circuit breaker. Install the circuit breaker according to the manufacturer's instructions. Connect wiring from the circuit breaker to the incoming power side of the control enclosure, ensuring all connections are secure.

  4. Power Up the System

    Remove any protective coverings from components. Ensure the operator handle is in the 'OFF' position. Close and latch both the Sequestr and control enclosure doors. Turn on the feeder disconnect switch and then flip the operator handle to the 'ON' position. Verify that the system operates correctly.
